Director Dan Neenan tells Brownfield Midwest hog farms are the most at risk.

“As the foam starts coming through the slats, the farmer wants and needs to get it out of there and they agitate the pit.” He says, “When we brake the seal of that foam, methane comes up in a large area of gas and is looking for a spark.”
